Uses
The timber is used as dungun. It is excellent firewood, having a high energy value. Moreover, the wood is suitable for the production of wrapping, writing, and printing paper. The bark contains tannin and is used for toughening fishing nets. An extract from the seeds is used medicinally in cases of diarrhoea and dysentery. The seeds are occasionally eaten. In the Philippines the roots are used as a fish poison.

- Leaves simple, silvery scaly beneath, petioles 0.5-1(-2) cm long, stout.
- Panicles lax, up to 18 cm long.
- Fruit ellipsoid, with a rudder-like ridge, glabrous and glossy.
